Thermal imaging roof survey in Whitwell, Hertfordshire
A careful look at the roof at your property in Whitwell, and put it all in a written report with photos.
- Thin or uneven insulation in the roof
- Water that travels before it shows
- Heat escaping through the roof
About our thermal roof survey in Whitwell
A thermal camera can help when the cause of damp is not obvious. Leaks frequently run along a roof before they appear on a ceiling, and temperature patterns can help us trace where it may have come from. We combine the images with a visual inspection and moisture readings, so the findings do not rely on the camera alone. If you’ve noticed cold areas below the roof and damp where roofs meet walls and chimneys, a survey will tell you what’s going on.
Somewhere as small as Whitwell, older roofs are often steep and partly hidden by trees or outbuildings. A drone and a thermal camera each give a view you cannot get from the ground. Both the forecast and the airspace are checked first, and the journey is planned beforehand. Older roofs with steep slopes and tall chimneys are where the extra view helps most.
The Standard Survey adds moisture detection, a structural check and a follow-up consultation. The Premium Survey adds thermal imaging, drone inspection where applicable, structural analysis and an in-person consultation.

Why it’s worth a survey now in Whitwell
Wet insulation under a flat roof doesn’t dry out on its own while the covering stays on. In time, it stops insulating properly and can damage the deck. Finding the wet areas sooner keeps the work smaller. Outbuildings and barns around Whitwell are easy to forget, but a failed roof there can spoil what’s stored inside. A quick look before winter can save a lot.
Every price we give includes VAT. Our price is from £400, including VAT. You will know the price for your roof before you book.

Take a look at what a roof survey costs and two real surveys.
What this survey can’t tell you
Without opening up the roof, some things stay hidden, and that sets some limits:
- Reliable images in rain, strong wind or on a wet roof surface
- An energy rating for the building
- Hidden layers that need to be opened up to check
Not sure which survey suits your roof? You can phone 07833 053749 or email us and we’ll tell you. What a survey covers and does not.
What this survey covers
- Pitched roof slopes
- Commercial roofs
- Ceilings below the roof
- Insulated roof spaces
- Flat roofs
- Loft conversions
How it works
Before we start, let us know why you’ve booked: a purchase, a leak, a storm, new work or simply peace of mind. It helps us focus on what matters most to you. Most visits take about 1–2 hours at a house, including the thermal images, and around 3–4 hours for a commercial roof. In a hamlet or village like Whitwell, a postcode doesn’t always lead to the right gate, so a few directions, or a note of a nearby landmark, help us arrive on time. The visit itself is the same as anywhere else.
- We start with the roof, its history and any signs of damp or heat loss.
- We check the conditions and note how they may affect the images.
- We inspect the roof and take thermal images during the same visit.
- Moisture readings are used to check what the camera shows.
- The Premium report reaches you the same day, and we go through it with you in person.
Getting ready for the survey
- For flats, check roof access has been agreed
- If you are buying, let the agent know when we are coming
- Find any records of previous roof work
How to book
A quick phone call is usually the easiest start: ring 07833 053749 or use the contact form. The price is agreed before a date is set.
Advice
DIY checks: what’s safe
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, as it helps a surveyor trace the cause.
Watch the gutters in a downpour, from a window or the ground. Overflowing water can be a sign of a blockage or a gutter that has dropped.
When to book a survey in Whitwell
Buyers sometimes want more than a visual look at the roof. A Premium Survey adds thermal imaging, a drone inspection where applicable and a same-day report, which helps when timescales are tight.
A survey can pick up problems such as:
- Heat escaping through the roof
- Gaps in loft insulation
- Ceilings that feel colder in places
- Wet areas near outlets and upstands
For site and facilities teams at buildings such as St Paul's Walden Primary School, big roofs are where photos from the air and thermal images show the most at once.
What to check before booking
- Whether the loft space is looked at, where there is one
- Whether any drone flown is registered with the CAA
- Whether they hold professional indemnity and public liability insurance
- Which parts of the roof they’ll actually see

Tips from our surveys
From years of surveys, a few habits stand out:
- Clear leaves from outlets and gutters each autumn
- Tell us where and when you’ve seen damp or stains
- Remember the conditions on the day affect the results
- File the images with your roof records
Once we have been, the thermal images, photos and readings go into a single report. Each image is explained in plain words, alongside what we recommend. With a Premium Survey, you get the report the same day.
After repairs or a new covering, a later survey can confirm things are dry, when the conditions are suitable.
Common questions in Whitwell
Are there drone restrictions around Whitwell?
Normally it comes down to two things: the airspace at the address and the weather. Whitwell is about 1 mile from the edge of the flight restriction zone around Luton Airport. We check the exact boundary for the address before flying, and if the roof falls inside it, we ask for permission first. The flight also waits for calm, dry weather, and the rest of the survey doesn’t depend on the drone.
Does a conservation area affect roof work in Whitwell?
You can check whether a building is listed on Historic England’s list, and your council can tell you if it’s in a conservation area. If a home is listed, changes that affect its special interest need listed building consent, and in a conservation area re-roofing in different materials may need permission.
Can a thermal camera see water?
No, not on its own. It shows surface temperature, and wet areas can show up because they hold heat differently. That’s why we check any patterns with moisture readings.
Is thermal imaging included in your surveys?
It comes with our Premium Survey, which starts from £400. The Premium Survey also covers a full inspection, drone inspection where it applies, structural analysis and a report on the same day.
Does the weather affect a thermal survey?
The weather makes a real difference. It works best after a sunny day, with a dry roof surface and little wind. Rain, wind and heavy cloud can weaken the patterns, so we discuss the forecast when booking.
What will the report tell me?
It works through the roof part by part, in writing and with photos. Points are put with the most urgent first where relevant.
Can you use a thermal camera on a sloping roof?
It can show heat loss and some damp, but it has more limits there. Our report is clear about what can be read from them, and we check them with a visual inspection and moisture readings.
Flying and imaging in Whitwell
Whitwell is about 1 mile from the edge of the flight restriction zone around Luton Airport. If your survey includes the drone, the exact boundary is checked for the address first. Older houses in the South East frequently have slate or clay tile roofs, while many later estates have concrete tiles, and flat-roofed additions turn up almost everywhere. Where a roof is steep, tall or hard to see from ground level, drone photos and thermal images add detail.
Historic houses such as Shaw's Corner, about 2.9 miles south, show how far back building around Whitwell goes. For older roofs nearby, a look by drone or thermal camera is a hands-off way to check condition. Take an older house close to All Saints Church: steep roofs, tall chimneys and hidden valleys can be hard to see from ground level, and that’s where a view from above or with a thermal imager helps.
